MCO-2065: Move systemctl execs to dbus calls - #6421
Conversation
Replace direct systemctl exec calls with a systemd abstraction layer that uses the coreos/go-systemd library. The new SystemdManager factory pattern improves performance, maintainability, and testing by introducing easily mockable interfaces and enabling connection reuse. There are two ways of using the new interfaces: - DoConnection() for single operations with automatic cleanup - NewConnection() for batching multiple operations on one connection Signed-off-by: Pablo Rodriguez Nava <git@amail.pablintino.com>

WalkthroughThe daemon replaces direct ChangesSystemd D-Bus abstraction
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to This PR replaces direct systemctl calls with D-Bus-backed systemd operations, but the current head still has unbounded calls, eager connection setup on workflows that may not need systemd, a preset path using a non-managed bus connection, and ignored CRI-O reload failures. These can hang updates or kubelet recovery, cause unrelated actions to fail, or leave stale runtime configuration, so the PR is not merge-ready until the major issues are fixed or explicitly accepted.

Fix the struct field alignment so gofmt passes.
Line 40 breaks the alignment of the field block. gofmt aligns all field names and types in one block to the same column, and OnReloadDaemonFunc is the longest name. The verify job runs gofmt, so the current layout fails the build.

coreos go-systemd v22 dbus PresetUnitFilesContext method
💡 Result:
The coreos/go-systemd/v22 library does not contain a method named PresetUnitFilesContext. Upon reviewing the dbus package API [1][2], which interacts with the systemd D-Bus interface (org.freedesktop.systemd1.Manager) [3][4], there is no implementation of the PresetUnitFiles or PresetUnitFilesContext methods. The available unit management methods in the v22 dbus package include: EnableUnitFilesContext / EnableUnitFiles [3][4][5] DisableUnitFilesContext / DisableUnitFiles [6][7] LinkUnitFilesContext / LinkUnitFiles [6][5] PresetUnitFiles is a valid method within the native systemd D-Bus API, but it is not currently exposed via a dedicated method in the go-systemd/v22/dbus package [3][4]. If you need to invoke PresetUnitFiles, you must perform a raw D-Bus call using the connection object's underlying systemd manager object [3][4].

Create the D-Bus connection only when a systemd operation requires it.
These workflows now fail when D-Bus connection setup fails, even if the requested work needs no systemd operation. This affects reboot, none, and drain-only post-config actions. It also affects stale file cleanup when no stale unit needs a preset.
Create the connection lazily in the service-action branches. In deleteStaleData, create it only before the first required presetUnit call.

Bound all systemd D-Bus operations with timeouts.
The current calls use context.Background(), so an unresponsive systemd service can leave update or recovery flows waiting indefinitely. Use operation- or workflow-scoped timeout contexts and pass them through NewConnection, DoConnection, shared-connection operations, and listSystemdUnits. Apply the same bounded context to the reload in syncNodeHypershift and to the stop, daemon-reload, and start operations in the certificate writer.
